An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used ... Found on http://en.wikipedia.org/wiki/OLED
In light emitting diodes (LEDs) based on inorganic light emitting materials, some of the photons released by the inorganic materials are also reabsorbed by them. In organic light emitting diodes (OLEDs), which produce light using the same electron/hole recombination method as LEDs, the frequencies of light absorbed by the light emitting materials l...
